Was I supposed to have picked up my bag in AMS even though it was tagged all the way to HER?
No. If it's checked through and there is a big HER on the baggage tag, you can't pick it up since they not supposed to put it out on the carousel in AMS in the first place.
The typical cut off time for not checking baggage through is 24 hours, which turns a "layover" into a "stopover".

If you purchased your Ticket through Delta, they will be responsible for your baggage. You should file a claim through the Delta baggage claim website.
They will then take care of your reimburs*m*nt and then bill the baggage handler internally.
Also, if they checked your baggage through, which is a normal thing outside of the US, even for long layovers, you have done nothing wrong by not picking up your baggage.
